Voice Cloning in Japanese: how it works

Voice cloning copies the sound of a voice from a short recording and lets it say anything you type. With Japanese text, the cloned voice speaks Japanese with natural Japanese pronunciation, so you can create narration, dubbing or personal messages in a voice you already know.

Japanese is spoken almost entirely in Japan and is written with three scripts together: kanji (Chinese characters), hiragana and katakana. It uses pitch accent, and politeness levels are built into the grammar. With about 125 million speakers, it is a large audience to reach.

  1. Your own voice in JapaneseRecord yourself once and create Japanese voiceovers without recording every line.
  2. Consistent channel voiceKeep the same voice across all your Japanese videos.
  3. Reach new audiencesUse your voice to speak Japanese, even if you do not speak it fluently.

Tips for the best Japanese results

  • Use a clean recording of 10 to 30 seconds, with no music or echo.
  • Speak naturally in the sample; the clone copies your tone and pace.
  • Only clone your own voice or a voice you have permission to use.
  • Write names in hiragana or katakana if the kanji has several possible readings.
  • Use Japanese punctuation (、。) so the pauses fall in the right place.
